The strength-ductility paradox originally referred to the fact that the plasticity of titanium is improved when subjected to high-pressure torsion. This is also known as the SPD-paradox, where SPD is the initialism of severe plastic deformation. Today, we know that short-term annealing of the deformed material increases the strength and ductility simultaneously. The same phenomenon is also observed in other pure metals, in alloys and in metal-matrix composites.
The book reviews the strength-ductility paradox in a wide range of materials, and the range of mechanisms involved. The book references 119 original resources with their direct web links for in-depth reading.
